I VERNON BOYLE, OF PATERSON, NEV JERSEY.

FALLER FOR 'THE STOP-MOTIONS 0F WINDING AND SPINNING MACHINES.

SPECIFICATION forming part of Letters Patent N 0. 452,066, dated May 12, 1891.

Application filed August 7, 1888. Serial No. 282.17 9. (No model.)

To a, whom it may concern:

Be it known that I, VERNON ROYLE, of Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful Improvement in Fallers for the Stop-Motions of Winding and Spinning Machines, of which the following is a specification, reference being had to the accompanying drawings.

Myinvention relates to that class of fallers in which a wire arm having a thread-guide at one end is attached to a hub axially bored to fit loosely upon a pivot or pin.

I will proceed to describe the improvement, and afterward point out its novelty in claims.

In the drawings, Figure 1 represents a plan view of a faller-frame and fallers embodying my invention; Fig. 2, a vertical sectional view corresponding to Fig. 1; Fig. 3, a plan view, on a larger scale, of my improved faller; Fig. 4, a side view, part section, corresponding to Fig. 3; Fig. 5, a transverse vertical sectional view on line a: as of Fig. 3.

Like letters of reference indicate corresponding parts in all the figures.

Adesignates a frame in which are mounted four fallers B. One such frame may be employedfor each spindle in a machine for doubling silk.

Each faller B consists of an axially-bored hub a, preferably of metal, having in or around its circumference an annular groove 1), and of a wire arm 0, having a thread-guide d at one end, and bent at the other end nearly or quite around the hub, tightly encircling the said hub within its circumferential groove, the said arm being thereby firmly and rigidly secured to the hub without the aid of solder or other fastening device.

The axially-bored hubs a fit loosely upon a pivot or pin e, to which they are journaled, and which is supported by the frame A. The hubs have a considerable length, which gives themalongbearinguponthe'pine. Thelength of the said bearing prevents sidewise movein cut or looseness of the projecting end-of arm 0. As here represented, the pin or pivot econ sists of a wire,which has its end portion f bent laterally and forked, as at g, to engage'one side portion of the frame A, and thereby hold the pin 6 in place. Upon the same pin 6 is journaled orpivoteda balanced frame h, the back portion of which is made of greater weight, so that it normally maintains the position shown in Fig. 2. t' isawire provided for con necting the balanced frame h by suitable mechanism with the flier of a spindle. When a thread breaks, the faller, through the thread-guide of which it is placed, drops downward upon the frame h to the position shown in dotted lines in Fig. 2, and by its weight tilts the balanced frame h downward and, acting through the wire 2' and intermediate mechanism, stops the flier of the spindle. Thread-guide 01 may have any suitable form as a loop through which the thread passes, and the loop may be protected by a ring or thimble preferably of porcelain.

By making the Wire of the arm to fit tightly in the circumferential groove between the side faces of said groove and by making it tightly embrace the hub around the bottom of the groove, no other fastening of the arm to the hub is necessary to firmly secure it thereto.

What I claim as new, and desire to secure by Letters Patent, is.

A faller consisting of a circumferentiallygrooved and axially-bored metal hub and a wire arm bent at one end to tightly encircle the said hub within its circumferential groove and so secure itself thereto and having a thread-guide at the other end, substantially as specified.

VERNON ROYLE.
